Kidney health is often overlooked until problems become severe. These vital organs work quietly at night, filtering waste and balancing fluids while you rest. However, subtle warning signs during the night can reveal underlying kidney damage. Recognizing these rare symptoms early may help prevent serious complications.
1. Frequent Nighttime Urination (Nocturia)
Waking up multiple times during the night to urinate is not always just a sign of aging or drinking too much water before bed. It can indicate that the kidneys are struggling to filter waste effectively. Damaged kidneys may allow protein or blood to leak into urine, which changes bladder function and leads to increased nighttime urination.
2. Unexplained Itching or Restless Skin
Chronic kidney problems can cause waste to build up in the blood, leading to itchy skin, especially noticeable at night. If the itching is persistent and not linked to allergies or skin conditions, it may be a signal that your kidneys are not filtering toxins properly.
3. Swollen Ankles and Feet After Lying Down
When the kidneys are weak, they cannot remove excess sodium and fluids efficiently. At night, as the body rests, fluid redistribution can cause swelling in the ankles, feet, or even around the eyes. If swelling appears regularly at night or in the morning, it may be linked to kidney dysfunction.
4. Nighttime Cramps and Muscle Twitches
